We need to call for x minute
+ Phone Company A charges a monthly fee of $42.50, and $0.02 for each minute talk time. So we have to spend: <span>$42.50+ $0.02x
+ </span>Phone company B charges a monthly fee of $25.00, and $0.09 for each minute of talk time. So we have to spend: <span>$25.00+ $0.09x
We solve for x: </span>$42.50+ $0.02x> <span>$25.00+ $0.09x
or </span>$42.50- $25.00 > $0.09x- <span>$0.02x
and we have $0.07x<$27.50
or x< 27.50:0.07 and x< 393.86
The answer is:
If we have to call much time, at least 394 minutes, we should choose A
If not, choose B</span>
2 miles-12 min.
3 miles- 18min
4 miles-24 min
5 miles-30 min
3 miles- 18
4 miles-24
5 miles-30
6 miles-36
Yes they are the same
The correct answer is A. All triangles' interior angles equal 180.
The answer would be (-3+18) + (i +5i)
This is because changing the order of the numbers does not change the sum
